Application file My invention relates to s combination tool, particularly suitable for finishing the ends of bowling` 4eilley pins, end has reference inore particularly to acoinbinetion tool, the diilerent parts of which can each be ezisilj,v sharpened and when so sharpened, can be easily assembled and their relation will reinain such es to properly finish the lower end of e bowling,` alley pin..

ln the appended drawing, forming; part oi' this application,

lEigiire 1 is a vertical section. on line iwi, Figure 2;

Figure 2 is a top plan View of the tube embodying` my invention; and

Figure 3 is s bottoni plan View or' seine.

Referring to the drawings, 5 is s drill, the shank of which is secured in the bore of counter-sink G. The counter-sink 6 is in. turn supported within the bore of a le ce cnt* ter T. The face cutter carries a bell shaped cutter 8 which has a.. plurality of cutting edges 9, projecting1 above the tace cutter to finish the lateral .lince oi" the bowling alley pin neer the bottoni, `which bottom finished hy the hice cutter.

rhe bell shaped cutter 8 is ineinta'iined in the desired position on the ffice cutter 7 by si pin ll which foi-ins s rest for e cnt-ort l2 in thc bell shaped cutter S. rllhis cylindrical portion encloses the upper part cf the face cutter and the pin ll therein serres as a driver for the bell shaped cutter, but in addition thereto, it set screw is provided 'for locking; the bell cutter 8 to the lisce cutter 7. This set s rew is not shown in the drewings.

The coiintensinlr G entends through the entire length of the face cutter 7 end projects the desired distance above, and this position is controlled by a set screw 1? which serves to lock the drill 5 in the counter-sinh G. ln addition, this set screw 1.3 serves as ineens for interlocking` the fece cutter with Tune 20, i925.

i A set screw lll is pronce cutter for locking the .f'oiinterto the :fece cutter. The connteisinlt G hns at the rear end thereo'j on enlarged portion L5 which is sdfipted to lit a late spindle or n inotor share, es s cese insy be, sind to which the combinet'on tool may be secured by ineens of a set screw 1G.

The drill 5 projects ont ot' the countersinl and entends out of the bell shaped eimer 8. rllhis drill serves as a pilot forthe conibin .tion toch Fri the above description, it will be seen that the four tools forming the single teol can esch be independently sharpened end the i/'erions screws serre, in addition to securing the tool. in their proper rel-aliens,y es n'ieens oit interlocking the various tools so to provide ai more solid combinstion tool for finishing` the lower ends of bowling alley pins.
